PEX, PP-R or copper — what to choose
Material = tools + skill + service in 10 years. Basics: pipes and fittings.
Comparison
| PP-R | PEX | Copper | |
|---|---|---|---|
| Joint | Welding | Press / system fittings | Soldering / press (by type) |
| Flexibility | Stiffer | More flexible runs | Depends on the tube |
| Examples | Rozma 20, 25, Peštan 20, glass fibre | Viega Pexfit Pro 25 | Separate skill/cost; this wave focuses on PP-R/PEX |
| When | Classic hot/cold line with welding | Flexible route, press installer | Special projects / existing copper system |
What not to mix up
- PEX fitting on PP-R “because 20 mm”.
- For hot water — check PN/temperature — parameters.
Pipes · compression.
